ESCALATOR |
|
An escalator is a conveyor transport device for transporting people, consisting of a staircase whose steps move up or down on tracks that keep the surfaces of the individual steps horizontal.
A moving walkway, moving sidewalk, travelator, or travellator is a slow conveyor belt that transports people horizontally or on an incline in a similar manner to an escalator. In both cases, riders can walk or stand. The walkways are often supplied in pairs, one for each direction.

HEALTH |
|
Health is a term that refers to a combination of the absence of illness, the ability to cope with everyday activities, physical fitness, and high quality of life. In any organism, health can be said to be a "state of balance," or analogous to homeostasis, and it also implies good prospects for continued survival. Wellness is a term sometimes used to describe the psychological state of being healthy, but is most often used in the field of alternative medicine to describe one's state of being.

PUBLIC HEALTH |
|
Public health is concerned with threats to the overall health of a community based on population health analysis. Many organizations define health and how to promote health differently. The World Health Organization, the United Nations body that sets standards and provides global surveillance of disease, defines health as: "A state of complete physical, mental and social well-being and not merely the absence of disease or infirmity."
